Test if UI element is visible on screen

Hi,

I am trying to test if a UI element is visible on the screen. Im currently using a Image control, and would like to know if its visible by the camera, or if its outside of its bounds. I cannot seem to find a way to determine this, and as we do not have a renderer component I cannot do a GeometryUtility.TestPlanesAABB test.
Any help would be appreciated.
